Breakup of quantum liquid filaments into droplets
Francesco Ancilotto, Manuel Barranco, Marti Pi
We have investigated how the Rayleigh-Plateau instability of a filament made of a 41K-87Rb self-bound mixture may lead to an array of identical quantum droplets, with typical break…
Vortex properties in the extended supersolid phase of dipolar Bose-Einstein condensates
Francesco Ancilotto, Manuel Barranco, Marti Pi +1
We study the properties of singly-quantized linear vortices in the supersolid phase of a dipolar Bose-Einstein condensate at zero temperature modeling Dy atoms. The system…
Towards a QMC-based density functional including finite-range effects: excitation modes of a K quantum droplet
V. Cikojević, L. Vranješ Markić, M. Pi +2
Some discrepancies between experimental results on quantum droplets made of a mixture of K atoms in different hyperfine states and their analysis within extended Gross-Pitae…
Rotating mixed He-He nanodroplets
Marti Pi, Francesco Ancilotto, Jose' Maria Escartin +2
Mixed He-He droplets created by hydrodynamic instability of a cryogenic fluid-jet may acquire angular momentum during their passage through the nozzle of the experimental a…
Self-bound ultra dilute Bose mixtures within Local Density Approximation
Francesco Ancilotto, Manuel Barranco, Montserrat Guilleumas +1
We have investigated self-bound binary ultra dilute bosonic mixtures at zero temperature within Density Functional Theory using a Local Density Approximation. We provide the explic…
Interaction-enhanced flow of a polariton persistent current in a ring
A. Gallemí, M. Guilleumas, M. Richard +1
We study the quantum hydrodynamical features of exciton-polaritons flowing circularly in a ring-shaped geometry. We consider a resonant-excitation scheme in which the spinor polari…
Quantum Magnetism with Mesoscopic Bose-Einstein Condensates
A. Gallemí, G. Queraltó, M. Guilleumas +2
Lattice gases in the strongly correlated regime have been proven to simulate quantum magnetic models under certain conditions: the mapping of the double-well system onto the Lipkin…
Robustness of discrete semifluxons in closed Bose-Hubbard chains
A. Gallemí, M. Guilleumas, J. Martorell +3
We present the properties of the ground state and low-energy excitations of Bose-Hubbard chains with a geometry that varies from open to closed and with a tunable twisted link. In…
Multidimensional Josephson vortices in spin-orbit coupled Bose-Einstein condensates: snake instability and decay through vortex dipoles
A. Gallemí, M. Guilleumas, R. Mayol +1
We analyze the dynamics of Josephson vortex states in two-component Bose-Einstein condensates with Rashba-Dresselhaus spin-orbit coupling by using the Gross-Pitaevskii equation. In…
Coherent Quantum Phase Slip in two-component bosonic Atomtronic Circuits
A. Gallemí, A. Muñoz Mateo, R. Mayol +1
Coherent Quantum Phase Slip consists in the coherent transfer of vortices in superfluids. We investigate this phenomenon in two miscible coherently coupled components of a spinor B…
Persistent currents with non-quantized angular momentum
A. Muñoz Mateo, A. Gallemí, M. Guilleumas +1
We analyze the generation of persistent currents in Bose-Einstein condensates of ultracold gases confined in a ring. This phenomenon has been recently investigated in an experiment…
Fragmented condensation in Bose-Hubbard trimers with tunable tunnelling
A. Gallemí, M. Guilleumas, J. Martorell +3
We consider a Bose-Hubbard trimer, i.e. an ultracold Bose gas populating three quantum states. The latter can be either different sites of a triple-well potential or three internal…
Mesoscopic Bose-Einstein condensates as quantum simulators
A. Gallemí, M. Guilleumas, R. Mayol +1
Mesoscopic interacting Bose-Einstein condensates confined in a few traps display phase transitions that cannot be explained with a mean field theory. By describing each trap as an…
The role of anisotropy in dipolar bosons in triple-well potentials
A. Gallemí, M. Guilleumas, R. Mayol +1
Mesoscopic samples of polarized dipolar atoms confined in three spatially separated traps conform an extended Bose-Hubbard Hamiltonian in which different quantum phases appear depe…
Propagation of collective modes in non-overlapping dipolar Bose-Einstein condensates
A. Gallemí, M. Guilleumas, R. Mayol +1
We investigate long-range effects of the dipolar interaction in Bose-Einstein condensates by solving the time-dependent 3D Gross-Pitaevskii equation. We study the propagation of ex…
